Specification of Letters Patent.

Application filed June 24, 1911. Serial No. 635,109.

To all whom it may concern Be it known that I, JERRY HiiBsoHMAN, a

, citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Aeroplanes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to air-ships, and more particularly to a novel means for adjusting the aeroplanes to control the airships while in flight.

This invention has for its object to provide an air ship of the mono-plane type having means for adjusting the planes on the opposite sides of the operators seat independently of one another, and to hold said planes in fixed position when so desired.

Another object of the invention is to provide swivel fixtures on the frame of the device to which guy wires extending from the ends of the planes are secured.

Another object is to provide an air-ship of the mono-plane type capable of maintaining its balance or equilibrium by swinging one or the other of the opposite planes in various positions.

Other objects will be apparent from the following specification, appended claim and drawings thereof in which:

Figure l is a plan view of an air-ship constructed in accordance with myv invention. Fig. 2 is a front elevation thereof. Fig. 3 is an enlarged detail view of a portion of the frame showing the method of mounting the areoplanes to said frames. Fig. 4 is a plan view of the inner'end of the planes showing the locking means. Fig. 5 is a side eleyation of the device showing by dotted lines various positions of the plane.

In the construct-ion of the air-ships the difiicult proposition is the provision of means whereby a craft may be brought to a balanced position after making ,a turn or encountering air currents which tend to cause an air-ship to lose its equilibrium and especially in an air-ship of mono-plane type.

My invention is intended to overcome the common objections in air ships without flexing the planes from a fixed position but by swinging the planes circumferentially from one position to another so as to cause the plane to pr sent a different angle to the wind and thereby vary the resistance thereon. and by moving both planes either forward or aft I can vary the major weight of the craft so as to cause the same to rise or lower itself as in ascending from or descending to the ground.

My device comprises a frame which is composed of the vertical bars 10, upper and lower cross bars 11 and 12 respectively, and the curved side bars 13, and to which frame is secured the planes 14 and 15, rudder 16 and the body 17 in which is a motor (not shown) which drives the propeller 18. The cross bar 12 is provided with ground wheels 19 and is also yieldinglyconnected with the vertical bars 10. Fastened to the bars 10 and bearing against the cross bar 12 are the c011 springs 20 which absorb the shock incident to the craft alighting from a flight.

The planes 14, made as shown in the drawings, are warped to the proper degree to maintain the craft in flight, and one end of each of said planes tapers to a reduced portion as shown at 21 which terminates into a handle 22. The reduced portion 21 is provided with an opening through which one of the vertical bars 10 is adapted to pass and mounted rigidly to each of the vertical bars 10 is a bearing member 24 upon which the portion 21 is adapted to bear. The member 24 is provided with a plurality of apertures 25, and pivotally mounted on the reduced end of the plane in proximity to the handle 22 is a pawl 26, which is adapted to pass through an aperture 27 in the reduced end of the planeand into one or another of the apertures 25 in the member 24, and said pawl is provided with a handle 28 to permit manipulation. A spring 29 is interposed between the reduced end of the plane and the pawl 27 so as to cause the pawl to normally engage one or another of the apertures 25. Bracket members 30 are secured to the vertical bars 10 and are adapted to receive one end of the guy wires 31 and 32, the opposite ends of which are secured to the planes near their outer ends, and the brackets 30 are-so mounted upon the bars 10 as to permit a swivel movement which is necessary when either of the planes 14 is moved from the position shown in the drawings, because if the brackets 80 were secured rigidly to the bars 10 either the wires 31 or 32 would break or the plane would have to warp to compensate for the increased distance. An operators seat 33 is carried by Patented Apr. 30, 1912.

the frame and is positioned within convenient reach of the handles 22.

It is obvious that by releasing the pawl 27 and swinging the plane on one side differently from that on the other, the resistance of the air on the two planes exerts dif ferent liftlng or sustalning powers on the air-ship and naturally the side of the craft receiving the least support tends to fall or dip, so that if an air current should tend to throw the craft out of balance the manipulation of the proper plane to reduce the lifting effort thereof on said craft, will cause that side of the craft to drop and overcome the unbalanced raising effects of the air currents.

I clairn In an airship of the mono-plane type, a frame comprising a horizontal frame, vertical and parallel bars carried thereby, planes pivotally mounted on said vertical bars, the inner ends of said planes being reduced to form handles, said reduced portions receiving said parallel bars and said handles extending between said bars for manipulation of said planes, swivel brackets carried by sad parallel bars above and below said planes, guy wires connecting said swivel brackets to the ends of said planes. a fixed plane secured to the rear of said frame and the area of each of said planes being in substantially the same plane.

In testimony whereof I aflix my signature in presence of two witnesses.
